What mythologies are associated with crows?
Lots, but they’re way more boring than the real stuff crows do! (I’m a biologist, not an anthropologist. These things tell you lots about people, but little about animals. IMHO) If you really must go after this material, try the links from The American Society of Crows and Ravens. I found a baby crow that must have fallen from the nest/been abandoned/is injured! What should I do? Probably you should put it back where you found it. If you don’t like that idea, contact a licensed wildlife rehabilitator. For a lot more on this topic, click here.
